How much is the import duty on veterinary antibiotic medicaments from China?

A shipment of veterinary antibiotic medicaments classified under HTS 3004.20.00 and made in China currently pays no U.S. import duty at all. The Column 1 general rate for this subheading is Free, and on the entry date priced here China is not caught by any Chapter 99 additional-duty program. That combination is rarer than it was two years ago, and worth knowing if you are comparing sourcing options.

The duty stack, line by line

There is only one duty line on this entry. HTS 3004.20.00.10 carries a Column 1 general rate of Free, and the engine finds no Chapter 99 additional duty for China on this code as of 2026-10-06. That can change with a single Federal Register notice, which is why the rate on this page is stamped with the measures version it came from rather than presented as permanent.

Worked example: a $10,000 shipment

Take one ocean shipment of veterinary antibiotic medicaments with an entered value of $10,000 — the customs value of the goods, before freight and insurance. The rate is Free, so the duty is $0.00. On top of the duty, the entry attracts a merchandise processing fee of $34.64 and, because it arrives by vessel, a harbor maintenance fee of $12.50. Duty and fees together come to $47.14, and the engine puts the landed cost of the goods at $10,047.14.

Scaling the value does not change that — the rate is ad valorem, so a $100,000 entry is still duty-free — but MPF and HMF do scale, and MPF is capped per entry. Run your own value, entry date and HTS code through the import duty calculator for the same calculation against the same engine.

What changed, and when

The rate here has been stable across the period we can price: an entry dated 15 October 2025 pays the same 0% that applies today. Stability is not a promise — Chapter 99 lists are amended by notice, sometimes with days of warning — but this subheading has not been a moving target from China.

An entry dated 15 May 2026 prices at 0%, the same total as today. The Section 122 balance-of-payments surcharge in force over that window (24 February to 23 July 2026, since expired) did not attach to this code.

MPF, HMF and what else lands on the entry

Duty is not the whole bill to Customs. The merchandise processing fee is ad valorem with a statutory floor and ceiling per entry — $34.64 on this $10,000 example. The harbor maintenance fee is charged on vessel arrivals only, $12.50 here; the same shipment flown in would pay no HMF.

Not in any of these figures: antidumping and countervailing duties, excise taxes, quota charges, bond costs, and the freight and brokerage that make up the rest of your landed cost. AD/CVD is worth checking before you commit to a supplier — it is assessed on the producer and exporter, not just on the HTS code, and it can dwarf the tariff.

U.S. imports of 3004.20.00 from China

Between March and July 2026 the U.S. imported $665 million under HTS 3004.20.00 from the 55 origins in this dataset; $78 million of it — 11.8% — came from China, making China a mid-sized supplier on this subheading. The largest were India (30.8%), Italy (15.2%), China (11.8%), Belgium (7.6%) and Canada (6.5%).

Census also reports duty actually collected: entries of HTS 3004.20.00.10 from China paid an average effective duty of 10.00% of value over those months. That is above the 0% priced here, which usually points to other 10-digit lines in the subheading, or to measures that attach to the goods rather than the code — antidumping and countervailing orders being the usual cause. Treat it as a sanity check on your own numbers, not a forecast of your entry.

Planning around this number

Classification drives this: the page prices HTS 3004.20.00.10, the largest 10-digit line under 3004.20.00 for China by import value that the tariff engine prices (the Census extract also reports a larger line under a statistical suffix the engine does not carry), and a neighboring line in the same subheading can carry different Chapter 99 exposure. Entry date matters as much as origin — the gap between the dates above is a change in law, not in your goods.
